I tried to login to Diablo 3 and get a message stating wrong password.

I reset my password, but when I enter the password I remember, it says that I can't use the same password with existing password.

Then I change password to a different password anyway.

I tried to login again and the authenticator keeps giving the wrong number.

So I can't login to the battle net and then I can't ask support because only those who login can submit ticket.

In short, trying to login to my account gives error message authenticator code is wrong. Trying to login to Diablo 3 gives error message wrong password.

  • Mobile Authenticator? Close the app and re-open it. I had that happen to me.

  • Thanks everyone. All I need to do is to "sync" that mobile authenticator and everything back to normal.

  • Blizzard's support stinks. And this page getting 55k views shows that blizzard really need to improve its support system.

View their contact page here

You can call them at this number according to this site.

United States/Canada   1-800-592-5499
  • That's the same number for both countries. I wonder why the site even bothers putting them on separate lines.

  • I wondered the same thing. They might as well just put it like my post, and remove the "United States / Canada" lines, and just keep it North America.

Mobile Authenticator

Like fbueckert said in their comment, if it's a Mobile Authenticator, try closing and re-opening it.

Another possibility is that your Serial has got out of Sync. Which this means you will most definitely have to get in contact with customer support.


Since you can't log into your account, I'd recommend giving them a call. I've had both good and bad experiences while calling Battle.net/Blizzard.

North America

Hours: 7 am - 8 pm Pacific Time, 7 days a week
